Archimedes would be proud of the town of Rjukan, Norway. So would Sam Eyde.
Rjukan, home to about 3,500 residents and situated about 70 miles west of the capital, Oslo, has installed a trio of giant mountaintop mirrors to focus light into the valley town's square during the cold (and dark) winter months.
The U.S. government Tuesday announced new rules for snowmobiles in Yellowstone that should make the country's oldest national park cleaner and quieter.
The rules were 15 years in the making because of intense wrangling between snowmobile operators and environmentalists. But both groups support the plan and give credit to snowmobile makers for designing cleaner machines.

The National Oceanic and Atmospheric Administration, the federal agency charged with surveying the nation's navigable waters to help keep mariners off the rocks and out of the shallows, will cease printing paper charts after mid-April.
We're used to relying on antibiotics to cure bacterial infections. But there are now strains of bacteria that are resistant to even the strongest antibiotics, and are causing deadly infections. According to the CDC, "more than 2 million people in the United States every year get infected with a resistant bacteria, and about 23,000 people die from it," journalist David Hoffman tells Fresh Air's Terry Gross.
With a tiny clump of cells from a man's scalp, scientists have grown new human hair in the laboratory.
But don't get too excited. A magic cure for baldness isn't around the corner. The experimental approach is quite limited and years from reaching the clinic — for many reasons.
The scientists have grown the hair only on a tiny patch of human skin grafted onto the back of a mouse. And as wispy locks go, the strands are pretty pathetic. Some hairs were white, and some didn't even make their way out of the skin.
If you've flown across Nebraska, Kansas or western Texas on a clear day, you've seen them: geometrically arranged circles of green and brown on the landscape, typically half a mile in diameter. They're the result of pivot irrigation, in which long pipes-on-wheels rotate slowly around a central point, spreading water across cornfields.
Yet most of those fields are doomed. The water that nourishes them eventually will run low.
As we all know, Americans are living longer. Women especially.
But here's what you may not know: French, German, Swedish, Italian, Japanese, British, Dutch and Canadian women are living longer too, but their lives are getting longer faster than ours. Take a look at this from the National Academy of Sciences.
